Changes 0.2.3:
* Sieve filter tool: finished implementing basic functionality. It is not
  quite ready yet, but it is available for those willing to experiment
  with it (needs --with-unfinished-features config to compile). Also
  includes man page.
* Vacation extension now inhibits replies to messages from sender listed
  in :addresses, thus preventing replies to one of the user's other known
  addresses.
* Vacation extension: implemented the (draft) vacation-seconds extension.
  This also adds min/max period configuration settings. Refer to
  doc/vacation.txt for configuration information.
* ManageSieve: fixed bug in UTF-8 checking of string values. This is done
  by discarding the original implementation and migrating to the Dovecot
  API's UTF-8 functionality.
* Sieve command line tools now avoid initializing the mail store unless
  necessary. This prevents sievec and sieve-dump from failing when
  executed by root for example.
* Enotify extension: fixed inappropriate return type in mailto URI parse
  function, also fixing ARM compiler warning.
* Vacation extension: fixed handling of sendmail errors. It produced an
  additional confusing success message in case of error.
* Removed header MIME-decoding to fix erroneous address parsing. Applies to
  address test and vacation command.
* Fixed segfault bug in extension configuration, triggered when unknown
  extension is mentioned in sieve_extensions setting.

Log message:
Update Dovecot Pigeonhole plugin to 0.2.2 (goes with Dovecot 2.0.8).

* LDA Sieve plugin: started using Dovecot LDA reject API for the
  reject extension. This means that the LDA reject_reason and
  reject_subject settings now also work for Pigeonhole's LDA Sieve
  plugin.
* Did some work on the new sieve-filter tool. It is mostly
  functional, but it is not finished yet.
* Dovecot change: services' default vsz_limits weren't being enforced
  correctly in earlier v2.0 releases. Now that they are enforced, you
  might notice that the default limits are too low and you need to
  increase them. This problem will show up in logs as "out of memory"
  errors. See default_vsz_limit and service { vsz_limit } settings.
- Imap4flags: fixed segfault bug occurring in multiscript context.
- Added version checking to the ManageSieve settings plugin. This
  plugin was forgotten when the LDA plugin was updated with this
  change in the previous release.
- LDA Sieve plugin: fixed memory leak at deinitialization.

MASTER_SITES fix

Log message:
This package is part of the Pigeonhole project (http://pigeonhole.dovecot.org).
It adds support for the Sieve language (RFC 5228) and the ManageSieve protocol
(RFC 5804) to the Dovecot Secure IMAP Server.

The Sieve language is used to specify how e-mail needs to be processed. By
writing Sieve scripts, users can customize how messages are delivered, e.g.
whether they are forwarded or stored in special folders. Unwanted messages can
be discarded or rejected, and, when the user is not available, the Sieve
interpreter can send an automated reply. Above all, the Sieve language is meant
to be simple, extensible and system independent. And, unlike most other mail
filtering script languages, it does not allow users to execute arbitrary
programs. This is particularly useful to prevent virtual users from having full
access to the mail store. The intention of the language is to make it impossible
for users to do anything more complex (and dangerous) than write simple mail
filters.

Using the ManageSieve protocol, users can upload their Sieve scripts remotely,
without needing direct filesystem access through FTP or SCP. Additionally,
aManageSieve server always makes sure that uploaded scripts are valid,
preventing compile failures at mail delivery.

This package provides Sieve support as a plugin to Dovecot's Local Delivery
Agent (LDA) and Dovecot's LMTP service. The ManageSieve protocol is provided is
an additional service, next to Dovecot's own POP3 and IMAP services.
